I met once a boy and his sister. And thers family name was "Sveikata" So he was Sveikata and sisters second name Sveikataite. I met them in town name Mariampole. I Soviet union times town was caled Kapsukas. I remember them because the second name was strange and unjusual to me then. It means Health in Lithuanian :) I beleave their family is still living there. I Can ask my ount (she is neigbour) for more details if you want.
Sory for my bad english. I hope it was helpfull :)
